So I was going through this collection when I spotted this paperback cover and I said to myself “that’s certainly a head drawn by Barry Windsor-Smith.”

This isn’t a paperback collection of comics, but rather one of a series of prose adventure novels with, as one might guess, a kung-fu theme. As I’ve not read any of these, I am unqualified to comment on the quality of the writing, but a random flip through the book reveals the lines

As I recall, Smith did all the covers for this series except for the last one, which was by Dick Giordano.

As I further recall, Bill Pronzini’s book GUN IN CHEEK credits this series to the same guy who wrote the “Death Merchant” books, one of the longer lived of the “Executioner” imitations (Ron Goulart wrote another, “The Butcher,” which may be from where the confusion comes). The Pronzini book is a sort of “Golden Turkey Awards” for mystery and crime fiction. According to it, K’ing Kung Fu’s specialty was kicking men in the krotch–sorry, crotch. Thus, in the aftermath of one battle, the losers are memorably described as “killers with inflamed balls.”
